    [ https://issues.apache.org/jira/browse/HBASE-17273?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15954019#comment-15954019 ] 

Sean Busbey commented on HBASE-17273:
-------------------------------------

Do we need anything else here to get started? An update to the docs on coprocessors that calls out this location maybe?

> Idea here is a module where we can carry coprocessors that are of general utility. In particular, I am thinking of the coprocessor used by yarn timeline server v2 which does aggregating and then replacing increments with a sum cell. This seems generally useful. Other candidates might include our cross-row transactions coprocessor is another that could go here pulled out of hbase-server and so on.
> Currently only coprocessors bundled in hbase are examples and endpoints.
